Description
Technical field
The utility model relates to a kind of fault detect of intelligent breaker and the system that fault is got rid of automatically.
Background technology
Intelligent switchboard is three grades of equipment of distribution system, and each switch cubicle generally has been arranged in parallel 2-5 group intelligent breaker.Intelligent breaker is by the electrical wiring requirement, switchgear, measuring instrument, protective device and auxiliary equipment to be assembled in housing of sealing, consists of low-voltage distribution equipment.
Next intelligent breaker of ordinary circumstance can be controlled 2-20 load, and its principle (has only drawn 3 loads) as described in Figure 2 in this figure, and intelligent breaker 1 includes a plurality of output ports, and each output port all can connect a load 2.Intelligent breaker 1 generally need to manually be pressed closed button and just can make breaker closing after automatic disconnection.Closure mainly makes its closure and controls its closure by the intelligent electric control signal by mechanical key; The intelligent electric control mode is to be connected to a control port 11 of controlling breaker closing on intelligent breaker, and this control port 11 can be controlled breaker closing after receiving a closure signal.
Present this intelligent breaker, when appearring in load, situation can disconnect all load power sources, and the mode that needs to need artificial close circuit breaker, a this load to go wrong after artificial investigation load-reason all loads are disconnected, affected the use of non-load fault, brought inconvenience.Need the people for could artificial close circuit breaker making all loaded work pieces after fixing a breakdown, efficient is extremely low.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of system that intelligent trouble detects and Intelligent drainage removes of circuit breaker.
The technical solution adopted in the utility model is such: a kind of intelligent trouble of circuit breaker detects removal system, comprise intelligent breaker and a plurality of loads that are electrically connected with the output of this intelligent breaker, this intelligent breaker comprises that also one controls the control port of breaker closing, current acquisition module and the electric-controlled switch that is used for the collection load current value of all connecting between described intelligent breaker and each load; Also comprise a central processing unit, the data input pin that the output of each current acquisition module all is connected to this central processing unit is electrically connected, the on/off control input end of each electric-controlled switch all is electrically connected with the control output end of this central processing unit, and a control output end of this central processing unit also is electrically connected with the control port of intelligent breaker.
In above-mentioned technical scheme, described central processing unit is the arbitrary money processor in a single-chip microcomputer, DSP, ARM, FPGA, PLD, CPLD.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: intelligent decision load fault circuit, after cutting off the electric-controlled switch of this loaded line, automatically start circuit breaker, non-load fault can be restored electricity within several seconds, control intelligence convenient, facilitate load; The staff saves manpower as long as load fault is overhauled.
Description of drawings
Fig. 1 is the principle topological diagram that the intelligent trouble of the utility model circuit breaker detects removal system;
Fig. 2 is the topological diagram of prior art circuit breaker and load.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of intelligent trouble of circuit breaker detects removal system, comprise intelligent breaker 1 and a plurality of loads 2 that are electrically connected with the output of this intelligent breaker 1, the present embodiment is take 3 loads as example, this intelligent breaker 1 comprises that also one controls the control port 11 of breaker closing, current acquisition module 3 and the electric-controlled switch 4 that is used for the collection load current value of all connecting between described intelligent breaker 1 and each load 2; Also comprise a central processing unit 5, the data input pin that the output of each current acquisition module 3 all is connected to this central processing unit 5 is electrically connected, the on/off control input end of each electric-controlled switch 4 all is electrically connected with the control output end of this central processing unit 5, and a control output end of this central processing unit 5 also is electrically connected with the control port 11 of intelligent breaker 1.
Its operation principle or step are: central processing unit 5 is by the current value of the real-time collection load of current acquisition module 3, the reason that causes the circuit breaker automatic disconnection is exactly mainly that the load total current maximum current that surpasses circuit breaker causes, therefore when some load-reason caused that circuit breaker disconnects, the electric current of this load generally showed as large or becomes suddenly large.Central processing unit 5 can be stored the current value of each load of 5-30 in second, when or unexpected increase excessive due to certain load current cause that circuit breaker disconnects, loaded electric current will all become 0 this moment, this moment central authorities process 5 can be by storage the current value analysis judgement of each load of 5-30 in second be that the large electric current of which or which load causes, then disconnect by controlling the electric-controlled switch of connecting in this load that causes circuit breaker to open circuit, and then send close command to the control port of circuit breaker, this moment the circuit breaker auto-closing.This process probably only has time several seconds, can judge load fault, and the work that restores electricity of completing non-load fault, and the time is short, and is intelligent high, the time that reduces to investigate and human cost expenditure.
As preferred version, described central processing unit 5 is the arbitrary money processor in a single-chip microcomputer, DSP, ARM, FPGA, PLD, CPLD, is perhaps a PC.In the technical solution of the utility model, because loaded line may be more, preferably adopt DSP or arm processor chip, because the data-handling capacity of this two chip and arithmetic speed are all very fast.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
